Yes, this is you. I wonder in what context you want to use this sentence. And always, it's important to know the relationship between speakers.1. between families or friends// or to someone under your age 응, 이거 너야. / 어, 이게 너야. 2. in formal situations 네, 이게 본인이세요./ it's better to know how you call the person.
